The board was liquid damaged
I wasn't getting voltage at the fuse, replaced U9701 and got voltage. Now it appears the circuit is not being boosted to drive the backlight.
I also replaced 0910
I'm getting 14.3V on PPVOUT_SW_LCDBKLT on the LVDS connector but no backlight.
I'm guessing there is no boost?
Diode mode measurement on PPVOUT_SW_LCDBKLT is 0.608
SW via is blown?
How do check the SW traces?
